Sažetak
The presented investigation work investigates thermal properties of the ultra-high hardness (UHH) armour steel. Steel is distinguished with high hardness and strength. It is sold in the quenched or tempered state, because achieving planned hardness which has to be between 590 HB and 640 HB. In the frame of the investigation work the analysis of thermal properties of the steel was carried out on the device Hot Disk TPS 2200, which works according to the method of transient plane source (TPS) method. Measurements were carried out according to the standard ISO 22007. In addition to thermal properties we measured hardness and analyzed the microstructure of the steel. The study aimed to determine thermal properties at ambient and at elevated temperatures. The results have shown that thermal conductivity increases up to the temperature of 400°C. Analyzed steel can be classified as medium thermal conductive steel with an average value of thermal conductivity of 27.17 W/mK at ambient temperature.
